My friend and I each ordered an Android 4.2 dual core TV Box. We then bought wireless USB Keyboards to make it easier to type the names of tv shows when searching. My friend plugged his in and it started working immediately. I plugged mine in and nothing happens. It is as if it does not work at all. When plugging a flash drive into the USB port of my TVBox, it works fine. BUt the USB communicator with the keyboard does not work. The only difference between the use of my TV Box and my friend's, is that his is plugged in directly via Cat.5, and mine is hooked in via WIFI. Could that be part of the problem?
